CrystalDiskMark is a disk benchmark software that allows us to benchmark 4K and 4K queue depths with accuracy.
* Sequential reads/writes
* Random 4KB/512KB reads/writes
* Text copy
* Change dialog design
* internationalization (i18n)
Note: Crystal Disk Mark 3.0 Technical Preview was used for these tests since it offers the ability to measure native command queuing at 4 and 32.
In CDM we see incompressible data that ranges from sequential to random at high queue depths. The 335 Series 180BG breaks into the 25MB/s arena in 4K reads. After testing Vertex 3.20 we worried about the performance 20nm IMFT flash would deliver, but it looks acceptable now.
In the past we've spoken about the brick wall of performance that comes with 128GB SandForce drives. You can see the effect on the chart, the Vertex 3.20 and V300 directly under the 335 Series 180GB. There are many reasons to choose the Intel 335 180GB over a 120GB SandForce drive, and these results send a clear picture.
